A 38-year-old member asked:
how does exposure to germs affect the immune system and general health?

Infections good/bad: Can be good or bad. Germs (viruses, bacteria, parasites, etc) stimulate one or more response(s) by immune system to isolate and destroy the "attacker" which is usually good. However that immune response may be excessive leading to disease (ie autoimmune illnesses) bad. The improvement in childhood health may be contributing to the increase in allergy, the hygiene hypothesis, usually a negative.

Not enough protein: Generally not eating enough protein and consistently and eating carbohydrate will cause a surge in Insulin that will drive your blood sugar into the cells causing a sudden drop in the sugar levels in the blood causing a lower blood sugar or hypoglycemia.

Why is adjusting to flying from the east coast to the west coast generally considered easier than west to east coast?

Time + vs -: I believe this is one reason: if you generally are ready for sleep at 10pm eastern time and travel to the west coast, you would be ready for sleep at 7pm pacific time; not too hard to stay awake a few more hours. If you are ready to sleep at 10pm pacific time and travel to east coast, your body would not be ready to sleep until 1am. Trying to sleep 3 hours before you are ready can be difficult.

Not really: The uses of tampons or pads are a personal choice based on personal preference for handling menstrual flow. Pads may be better for extremely heavy menses.
